Power-Line Communications (PLC) Integrated
Analog Front-End Transceiver
General Description
The MAX2991 power-line communication analog front-
end (AFE) is a state-of-the-art integrated circuit that
delivers high integration and superb performance, while
reducing the total system cost. The MAX2991 is the first
AFE specifically designed for OFDM (orthogonal fre-
quency division multiplexing) modulated signal transmis-
sion over power lines. Operating in the 10kHz to 490kHz
band, the programmable filters allow compliance with
CENELEC, FCC, and ARIB standards using the same
device.
The MAX2991 transceiver provides two main paths:
transmit (Tx) path and receive (Rx) path. The transmit
path injects an OFDM modulated signal into the AC or
DC line. The transmit path is composed of a digital IIR
filter, digital-to-analog converter (DAC), followed by a
lowpass filter, and a preline driver. The receiver path is
for the signal enhancement, filtering, and digitization of
the received signal. The receiver is composed of a low-
pass and a highpass filter, a two-stage automatic gain
control (AGC), and an analog-to-digital converter (ADC).
The integrated AGC maximizes the dynamic range of the
signal up to 60dB, while the lowpass filter removes any
out-of-band noise, and selects the desired frequency
band. The ADC converts the enhanced and amplified
input signal to a digital format. An integrated offset can-
cellation loop minimizes the DC offset.
The MAX2991, along with the MAX2990 PLC baseband
modem, delivers the most cost-effective data communi-
cation solution over power-line networks in the market.
The MAX2991 is specified over the -40NC to +85NC
temperature range and is available in a 48-pin LQFP
package.
